Installation failing on Arch Linux Steamdeck

[sardior]

Howdy,
The Discover Software Center has the free version of FreeFileSync and I've found it to be really useful. So, I donated and received the Donation version. However, I can't find a way to install it on the Steamvalve Corp, Steamdeck which uses Arch Linux. When trying to run it from Dolphin File Manager there are not enough permissions granted to install. So, trying to run it from the Konsole (terminal) using Sudo it still cannot find directories to install the program. Thank you for a wonderful program. It would be nice to be able to use the enhanced features.

"Read-only file system"
Doesn't seem to be a FFS issue

Ah, so the FreeFileSync installer wants to control /usr/local/bin (normal behavior), but on this device, /usr/local/bin/ is mounted read-only. Perhaps you should try the per-user installation option. I expect it would deploy the binaries to ~/bin or ~/.local/bin/ (suggested by https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html). Hopefully your user's ~/.local/bin/ directory is readable.
Also, the per-user applications directory would be ~/.local/share/applications.

There is no ~/.local/bin/ directory. there is a ~/.local/ directory. And there is a ~/.local/share/applications directory. I just switched it to single user only and it finally installed. Thank you for your help.

It installed, but now won't run. It says that I don't have GTK2 installed. and I've looked for a way to install it and there is nothing helpful i've found to do that. -very frustrated now.

Added note, I think I found the program in the "Discovery" app which is the software installation app for SteamDeck. I reinstalled it with that and have the original version working again. It is odd that it works from that source, but will not install the donation version.

Welcome to Linux

In Arch Linux the package to install gtk2 is named gtk2, based on https://wiki.archlinux.org/title/GTK#Installation
